    使用 <el-table> 组件并传入 :data="categorys" 属性时，categorys 数组中的每个对象都将作为一行数据（row）传递到表格中。
在 el-table-column 的默认插槽中，可以通过插槽作用域访问当前行的数据。
Element Plus 为每个插槽提供一个包含 row 属性的上下文对象，其中 row 表示当前行的数据。
在 <template #default="{ row }"> 中，{ row } 是一个 JavaScript 解构赋值语法，它从插槽的上下文对象中提取 row 属性。
    因此，row 直接包含了当前行的数据，可以在模板中或者相关的事件处理函数中使用它。 -->
